Latest numerical weather prediction ensembles from the Korea Meteorological Administration and ECMWF indicate a highest temperature in Busan on June 22 most likely between 23–24 °C, driven by increased cloud cover, higher humidity, and possible passing showers linked to an approaching tropical depression south of the peninsula. These conditions are expected to limit daytime heating relative to clearer-sky climatology for late June, when average highs near 24 °C. Trader consensus around these outcomes reflects model agreement on modest instability and steering flow, while small probabilities for 25 °C or higher capture uncertainty in the exact timing of any clearing or reduced rainfall. Fresh KMA short-range updates and 00z/12z model runs over the next 48 hours will be the key catalysts for odds movement ahead of market resolution.
